Modify php script for search results

I have a php script that searches my database. I need it modified so that it does a better job at searching for results. Right now if it has one extra word it doesn't find anything. I need something that searches smarter.

This is what I currently have

$sql = "select * from questions where (Question LIKE '%$quest_search%' OR Answer LIKE '%$quest_search%') AND (active='yes')";

$result = mysql_query ($sql);

$count = mysql_num_rows( $result );

if($count == "0"){

$sql = "SELECT * FROM questions WHERE MATCH(Question,Answer) AGAINST ('$quest_search' IN BOOLEAN MODE) AND (active='yes')";
